Huge Error

I had a virus so I formatted and installed windows.I installed my MOBO's drivers and audigy 2 zs drivers sepraretly then rebooted but when I put in my ati radeon 9800 pro cd and install it on reboot this is what happens:
the boot screen shows,then it loads normally then it shows windows loading then after that its just a black screen for some period of time then an error message flashes for half a second and this is all I got out of it.:

driver got stuck in a infinte loop.this usually (got cut off)indicates with the device itself or (somethin) device driver programming the(cut off)incorreclty""check with your hardware device vendor for any driver updates. a1 information: P: 0x00000000EA (ox8499abe8,0x861ebc28,0x861cbb40,0x00000000001)

Then at the bottom it says something about memory dump or not being enough im not really sure but it ends saying something about memory.I did double check that my memory/vga are inserted and snapped properly into my MOBO.Anyways this is weird because I have installed this before obviously and why does it do this now?

 

did you use the latest Radeon drivers?
